Neha Ramu, 12-year-old Indian-origin girl in UK has stunned everyone after she scored an incredible 162 on her IQ test - even higher than Albert Einstein and Stephen Hawking.

Neha Ramu, daughter of an Indian doctor couple, achieved a score of 162 on a Mensa IQ test - the highest score possible for her age.

The score puts the tween in the top one per cent of brightest people in the UK and means she is more intelligent than physicist Hawking, Microsoft founder Bill Gates and scientist Albert Einstein, who are all thought to have an IQ of 160.

"Neha scored 162 on the Cattell IIIB test, putting her within the top one per cent of people in the country," a spokesman for British Mensa said.

Neha's parents lived in India before moving to Britain when their daughter was seven, 'The Telegraph' reported.

Neha had always performed well at school, but it was only when she took an entrance exam for her school, achieving a perfect score of 280/280, that they realised her potential.

She took the test for Mensa, a society for people with high IQs, two years later, and achieved the maximum possible score for someone aged under 18.
